Be it known that I, SYLVIA B. SARLEsa citizen `of the United States,resident of Hillsboro, county ot Traill, StateV of North Dakota, haveinvented certain newand useful Improvements in Flour Sitters, of whichthe following is a specification.

Flour sitters as usually constructed have an open bottom through whichthe flour falls during the sitting operation and the device cannot belaid down upon the table or mouldy ing board without some of the flourfalling through and becoming scattered, or more will be delivered thanthe cook requires.

The object of my invention is to provide an attachment for a floursitter by means ot which the open end can be easily and quickly closedso that the sitter may be placed upon the table or any other suitablesupport without danger of any ofthe flour falling out.`

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims'.

In the accompanying drawings forming part of this specification,

Figure 1 is a perspective view of a flour sitter .embodying myinvention, y

Figure 2 is a vertical sectional view of the same,

Figure 3 is a horizontal sectional view on line 3 3 ot Figure 2 showingdevice closed.

In the drawing, 2 represents the cylindrical portionot the sitter, madein the oreinary way, having the scooping lip 3 at one open end and alaterally projecting handle il. 5 is a sieve of suitable wire mesh,mounted in the cylinder, 6 is a rod having a crank 7 at the end of thehandle and provided in the cylinder with agitators 8 which, when the rod6 is revolved, sweep through the flour and agitate it in the screen andforce it through the meshesthereot. The lower end of the cylinder isusually open and the sifted flour is discharged by gravity therethrough.Oftentimes the cook wishes to lay down the sitter while it stillcontains some of the flour to attend to some other duties pertaining tothe cooking operation and this has been diicult because the liar otplacing the sitter on the table or moulding has the eilect ot sittingsome ot the flour through the screen and sometimes the sitter, althoughplaced very carefully on the table, may be jarred tor some reason andconsider- SIFTER,

ablenot the'fiour vbe shaken out'. 'To

avoid this diliiculty in the use of the ordinary sitter,- I provide adisc y9 secured-.on the open end ot the sitter by suitable means, suchas olipsl 10, which are preferably pressed or punched out of the thinsheet metal of which the disc 9 is composed. A second dise 1l isinterposedbetweenthe vdisc 9 and the wall of the sitterand centrallymounted on the disc 9 by means otra pivot pin l2. The two discs haveradial openings 13 therein which are adapted to register when the discl1 is set in one position, but when the said disc 11 is partiallyrotated, the openings in the disc 9 will vbe closed and lan impertoratebottom formed for the end of the sitter. A' lugV 141-.' is provided onthe disc 1l forming a convenient finger grip and a stop l5 is 'alsoformed on the periphery ot the disc 11 in position to contact with oneof the clips l() for limiting the rotation ot the disc in one directionwhile the engagement of the lugl 14C with the same clip will limit themovement'of the disc in the opposite direction.

I prefer-to arrange the parts so that when the lug 14 contacts with theclip the openings in the disc will be fully exposed for the discharge ofthe flour and when the disc il is rotated until the lug 15 contacts withthe clip the openings will be closed and fur ther discharge of the iourprevented. A bead 16 is formed on the end ot the sitter cylinder, asusually made, and my attachment can be easily slipped into place thereonby pressing the spring clips l0 over the bead so that the shoulders otthe clips will snap in the rear of the bead and lock the discs securelyon the cylinder. My attachment is therefore applicable Yto the ordinarysitter by the purchaser and need not be manufactured as a part ot thesitter or attached thereto at the tactory.

The device may also be readily removed whenever it is desired to obtainaccess to the sieve or when an unobstructed opening into the cylindertor any purpose is desired. The disc ll being between the disc 9 and thewall of the cylinder, it is evident that any accumulation of flour onthe disc 9 will be swept into the openings by the rotation of the disc1l.`

I claim as my invention:

l. The combination, with a sitterv conprising a cylindrical memberhaving an upper filling end, a sifting means intermediate its ends and asuitable handle, the lower end of said member having an encircling beadformed in its wall, a disc having openings therein fitting said lowerend and having spring clips to snap over said bead, a second disc alsohaving openings therein and centrally pivoted on said first disc, afinger o'rip on said second disc, and a stop for limiting the rotationof said second disc, said disc allowing the sitter to be placed uprightupon a support when not in use, preventing the premature discharge ofits contents.

2. A sitter comprising a sheet metal member having an open end toreceive the mate` rial to be sifted, and a screen and agita-ting meansmounted intermediate to the ends, an outside hand grip for said member,the lower end of said member having a bead r'ormed in the wall thereof,a cap litting the lower end o't` said member and comprising an outerdisc having a series ot radial openings therein and peripheral springclips formed to receive said rib and temporarily hold said disc thereon,a second disc ccntrally pivoted on said first named disc and also havingradial openings therein adapted to register with the openings in saidlirst named disc and said second disc having a peripheral lug projectingbetween said irst named disc and said bead to contact with one of saidspring clips and form a stop for limiting the movement of said seconddisc, and a peripheral linger grip provided on said second disc adjacentsaidr handle.

3. The combination with a sift-er open at each end and having anintermediate handle and provided with an interiorly arranged siftingmeans, the discharge end ol' said sitter being normally open to allowthe flow or" the sil'ted material therethrough, and means removablymounted on said discharge end and comprising relatively fixed androtating members adapted to alternately open and close the passagethrough said discharge opening, said means allowing said sitter to beplaced upright, when not in use, upon a suitable support and preventingthe premature discharge of the sitted material through said dischargeopening.

ln witness whereot, l have hereunto set my hand this 26th day of May,1920.
